i'd like advice on accepting things you can't change
like.. when you're rooteen is set in stone, you know what time you want to do something, how many of an item you want, etc, and then something changes out of your control and you have to settle for second best?

like: I like even numbers, and having to settle for an odd number (completely out of your control), or setting a certain time for something, and again, out of your control, it has to happen a few minits before/ after the given time

I'd really like tips on how to manage this. they needs to be more I can do than just go in to anxiety mode and have a meltdown about it.
